Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to track running equipment that allows vehicles running on a main track to also run traversing a transverse track laid at right angles to the main track. .

[Technical background of the invention and its problems]

In general, track running equipment that allows vehicles that have been traveling on the main track to enter a cargo loading/unloading area, load and unload cargo, etc., and then return the vehicle to the main track and run on the main track again. There is a known system in which a lead-in track that allows vehicles to enter the loading/unloading area from the main track is connected to the main track via a curved road, and vehicles are allowed to enter the lead-in track from the main track by switching points. In track running equipment where the main track and the service track are connected by a curved road in this way, the curvature of the curved road must be made sufficiently large to allow vehicles to run safely even on the curved road. The problem is that a large area of land is required to construct the curved road.

For this reason, recently, two lines with the same gauge as the main line are laid as lead-in lines at right angles to the main line with an interval corresponding to the distance between the front and rear bogies of the vehicle, and this pair of left and right lines ( Turntables are installed at the intersections of the main track (hereinafter referred to as the transverse track) and the main track, and the vehicle that has been traveling on the main track with the rotatable bogies at the front and rear of the car body facing in the front and back direction of the car body is The front and rear bogies are stopped at a position on the turntable, and in this state, the turntable is rotated 90 degrees so that each bogie is oriented in the width direction of the vehicle body, thereby allowing the vehicle to enter the traversing track. A method in which the vehicle runs sideways on the horizontal track of the lever to the loading/unloading area (the bogie at the front of the car body rides on one sideways track, and the bogie at the rear of the car body rides on the other sideways track, running in the width direction of the car body) Track running equipment has been proposed. In other words, this track running equipment allows a vehicle that has been running on the main track to enter the traversing track in the main track running position by simply changing the direction of the bogie, and travels traversely, as well as loading and unloading cargo, etc. After the vehicle has returned to the main track, the vehicle is returned to the main track by changing the direction of the bogie again. According to this track running equipment, the vehicle is returned to the main track by changing the direction of the bogie. Since it is no longer necessary, the land for laying the track can be reduced accordingly.

By the way, as a track running equipment for the above-mentioned method in which vehicles run sideways, one is currently being considered that has only one main track, but due to the cargo to be transported, the left and right wheel spacing is different. When trying to use different types of rolling stock, two main tracks with different gauges are laid in parallel, the first car runs on the first main track, and the second car runs on the second main track. It is necessary to run the vehicle. In such cases, it is normal for each vehicle to have a separate loading/unloading area for cargo, etc., but in some cases, the second vehicle may enter the loading/unloading area for the first vehicle. It may be necessary to load and unload cargo, etc.

However, since the second vehicle running on the second main track has the wheel spacing on the left and right sides of the bogie matched to the gauge of the second main track, the second vehicle running on the second main track has a different gauge than the second main track. Therefore, it is difficult to allow the second vehicle to enter the loading/unloading area for the first vehicle to load and unload cargo, etc.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to
A second vehicle running on a second main track, which has a different gauge from the main track of To provide track running equipment capable of running traversely on a traversing track.

[Summary of the invention]

That is, the present invention provides a first main track, a pair of left and right transverse tracks of the same gauge as the first main track, which are laid at right angles to the first main track, and the first main track. The vehicle is equipped with a first turntable disposed at each intersection with each first transverse track and a bogie that can rotate forward and backward, and runs on the first main track with the bogie oriented in the longitudinal direction of the vehicle body. At the same time, the first turntable turns the bogies toward the vehicle width direction, and the front bogie rides on one of the first transverse tracks, and the rear bogie rides on the other first transverse track. A second main track having a different gauge from the first main track is further laid parallel to the first main track in the track running equipment having a first vehicle that runs sideways in the width direction of the vehicle body. A pair of left and right second traverse tracks are laid at right angles to the second main track, and each of the second traverse tracks is installed so as to be linearly connected to the first traverse track with the first turntable in between. , furthermore, at the intersections of the rails of the second main track and the rails of each second lateral track, second
The second turntable is installed on both the front and rear sides of the car body, and four bogies with wheels arranged in a row along the center line of the bogies are installed on the vehicle running on the second main track. The second vehicle is arranged in a manner corresponding to the arrangement position of the second vehicle, and is configured to cause the second vehicle to travel in a traversal manner from the second traversing track to the first traversing track via the first turntable. In other words, the present invention provides a bogie for the second vehicle that runs only on one rail with wheels arranged in a row along the center line of the bogie, and also allows the bogie to run on only one rail on the second main track. By placing the second turntables on both the front and rear sides of the vehicle body in correspondence with the installation positions of a set of four second turntables, which are placed at the intersections of the second turntables and the rails of each second traverse track, When a No. 2 vehicle runs on the second main track with each bogie facing the longitudinal direction of the car body, the front and rear bogies on one side of the car body are on one rail of the second main track, and the bogies on the other side of the car body are on the second main track. When the front and rear bogies ride on the other rail of the second main track and each bogie is turned in the width direction of the car body by the second turntable, the bogies on both sides of the front of the car body ride on the other rail of the second main track. A second vehicle running on the second main track is mounted on the rails of the second main track, with the bogies on both sides of the rear of the vehicle facing the other rails of the second main track. The vehicle also enters a second traversal track that is linearly connected to the first traversal track with a different gauge, and travels traversely from the second traversal track to the first traversal track.

On the other hand, in FIG. 5, reference numeral 11 denotes a broad gauge second main line formed by laying two rails 11a with a gauge GA wider than the gauge G of the first main line 1 and the first lateral line 2. Second main line 1

Reference numeral 12 indicates the first turntable 4 at a right angle to the second main track 11 in order to allow the second vehicle 16 traveling on the second main track 11 to enter the shared loading/unloading areas A and C. A pair of left and right second traverse tracks are laid so as to be linearly connected to the first traverse track 2 across the two rails 2a of the first traverse track 2. It is constructed by laying two rails 12a with the same gauge as the first traverse track 2 so as to be connected in a straight line. In other words, the second traverse track 12 is connected to the first traverse track 2 via the rail 5 on the first turntable 4 by rotating the first turntable 4 by 90 degrees. be. Further, at the intersection of the second main track 11 and each second traverse track 12, one rail 11a of the second traverse track 11 and each second traverse track 12 are provided, as shown in FIGS. 6 to 8. A set of four cars is located at the intersection with one rail 12a of the track 12 and the intersection between the other rail 11a of the second main track 11 and the other rail 12a of each second traverse track 12. A second turntable 14 is disposed, and these second turntables 14
Each of the turntables 14 is provided with one rail 15 passing through its rotation center 14a. The second turntable 14 is rotated 90 degrees by a drive device (not shown), and the rails 15 on the second turntable 14 rotate the turntable in the state shown in FIG. By rotating the turntable, the rail 11a of the second main track 11 is connected, and by rotating the turntable to the state shown in FIG. 7, it is connected to the rail 12a of the second lateral track 12. It's summery. On the other hand, the second train running on the second main track 11
As shown in FIGS. 6 to 8, the vehicle 16 of
It has a configuration in which carts 17 are rotatably arranged on both front and rear sides of the vehicle body 16a in correspondence with the installation position of the second turntable 14, and each of the carts 17 is aligned with the center line of the cart. Wheels 1 in a row along
It is said that it is configured with 8. Note that the wheel 1
8 is located under the truck 17, but the wheels 18 are shown in solid lines in the drawing for convenience. Further, in this embodiment, the truck 17 has two axles at the front and rear,
One wheel 18 is provided on each axle.
It is a two-wheel platform with axles, and each wheel 18 is a double-flange wheel that has flanges on both sides and clamps the rail from both sides. Furthermore, each of the trolleys 17
Each of these is a drive truck equipped with a wheel drive electric motor 19, and each truck 17 is configured to travel at a constant speed.

Here, the mounting structure of the truck 17 to the vehicle body 16a will be explained.
21 is a center plate which is fixed to the vehicle body 16a and has a load-receiving surface on the lower surface; 21 is a center pin inserted into the center plate 20 and rotatably held via a bush 22; The lower end is attached to the frame of the truck 17 by a pin 23 so as not to restrict the pitching movement of the truck 17 and to prevent the truck 17 from tilting laterally. Further, the upper center plate 20 is provided with a center plate liner 2 on the upper surface of a lower center plate 25 provided on the frame of the truck 17 via a spring 24.
6, and is rotatably supported via the vehicle body 16.
The load a is applied from the lower surface of the upper center plate 20 to the lower center plate 25.
The vehicle body load is transmitted to the truck 17 via the spring 24 and the truck 17 receives the vehicle body load. Furthermore, a stopper 27 that is engaged with a part of the lower center plate 25 is protruded on the frame of the truck 17.
It is designed to be rotated together with the Therefore,
Even when the cart 17 is changed direction by the rotation of the second turntable, it rotates by causing sliding rotation between the upper center plate 20 and the lower center plate 25 while supporting the load of the vehicle body 16a. , attached to the frame of the truck 17 by pins 23
The center pin 21, which rotates at the same time, prevents lateral tilting while changing the direction. Therefore, if the above-mentioned truck mounting structure is adopted, the wheels 18 can be mounted horizontally in a row. The bogie 17, which is unstable with respect to the direction, can be maintained in a normal posture not only when traveling on a main track or a lateral track, but also when changing direction, thereby preventing it from overturning.

Thus, the second vehicle 16 has each trolley 17
faces in the longitudinal direction of the car body, and the front and rear bogies 17 on one side of the car body 16a ride on one rail 11a of the second main track 11, and the front and rear bogies 17 on the other side of the car body 16a ride on the second main track 11. While riding on the other rail 11a of the vehicle, the vehicle runs in the longitudinal direction on the second main track 11, and the direction of each bogie 17 is changed by the second turntable 14 to move onto the second lateral track 12.
The vehicle then enters the second traverse track 12 and travels laterally from this second traverse track 12 to the first traverse track 2. To change the direction of each bogie 17, first, the second vehicle 16 traveling on the second main track 11 is stopped when each bogie 17 is on the second turntable 14, and
This is done by rotating the second turntable 14 in this state (the state shown in FIG. 6). In this case, it is desirable that all the turntables 14 be rotated in the same direction at a constant speed, and in this way, the center of rotation of the trolley 17a is separated from the center of rotation of the turntable due to the accuracy of the stopping position of the vehicle 16. Even if the cart 17 rotates with sideways displacement as the turntable 14 rotates, all the carts 17 shift in the same direction together with the car body 16a, so there is no force on the turntable 14 or the cart 17. No force is applied. Then, when the second turntable 14 is rotated 90 degrees, each bogie 17 rotated by the turntable 14 and directed in the width direction of the car body is moved to the front part of the car body, as shown in FIG. The bogies 17 on both sides are connected to the second traverse track 12 on one side.
The bogies 17 on both sides of the rear of the car body are in a state where they are respectively opposed to the two rails 12a of the other second traverse track 12, so each bogie 17 is run in this state. If this is done, each bogie 17 can be driven onto each rail 12a of the pair of left and right second traverse tracks 12, as shown in FIG. 8, and the second vehicle 16 can be caused to traverse in the width direction of the vehicle body. Furthermore, the second traverse track 12 has the same gauge as the first traverse track 2 and is laid so as to be linearly connected to the first traverse track 2 with the first turntable 4 in between.
When the second vehicle 16 enters the second traverse track 12 and travels traversely, the first turntable 4 is rotated 90 degrees and the second vehicle 16 is moved along the second traverse track 12 via the rail 5 on this turntable 4. Rail 12a
If the rails 2a of the first traverse track 2 are connected, the second vehicle 16 can be moved from the second traverse track 12 to the first traverse track 2.
The second vehicle 16 is also used as a loading/unloading area for the second vehicle among the loading/unloading areas A, B, and C for the first vehicle 6. It is possible to load and unload cargo by entering loading/unloading areas A and C that are to be shared. In addition,
After loading and unloading cargo, etc., the second vehicle 1
6 can be returned to the second main line 11 again by following the procedure in reverse to the above, so a description thereof will be omitted. In addition, if the first vehicle 6 runs on the first main track 1 while the second vehicle 16 is entering the loading/unloading area and loading/unloading cargo, etc., The first turntable 4, which has been rotated so as to connect the second traversing track 12 and the first traversing track 2, may be rotated to its original state and the first vehicle 6 may be allowed to pass.

In addition, in the above embodiment, as shown in the figure, 4
Although a set of second turntables 14 are arranged to form a parallelogram, the second turntables 14 may be arranged to form a trapezoid, and even in that case, By arranging each truck 17 of the second vehicle 16 in correspondence with the position of the second turntable 14, it is possible to operate the vehicle in the same manner as described above.

Further, in the above embodiment, the second traverse track 12 is composed of two rails 12a, but the second
6 is relatively light and small, the second traversal line 12 may be composed of one rail. That is, FIG. 10 shows a second embodiment of the present invention, in which the pair of left and right second traverse tracks 12 are each linearly aligned with one of the two rails 2a of the first traverse track 2. The second turntable 14 is composed of one rail 12a laid so as to be continuous with the two rails 11a of the second main track 11 and the rail 1 of the second lateral track 12.
2a, and the second vehicle 16 consists of four bogies 1 with both flange wheels 18 arranged in a line along the bogie center line.
7 is arranged in correspondence with the arrangement position of the second turntable 14. In other words,
In this embodiment, when the second vehicle runs sideways, the bogies 17 on both sides of the front part of the car body 16a ride on one rail, and the bogies 17 on both sides of the rear part of the car body 16a ride on one rail. 2nd transverse track 1
2, and one of the two rails 2a of the first traverse track 2 is used to cause the second vehicle 16 to traverse to the loading/unloading area A.
In FIG. 10, the same components as those described in the first embodiment are designated by the same reference numerals, and the explanation thereof will be omitted.
